Cool Black Hole Video by Kurzgesagt

A couple of weeks ago I watched a very cool black hole video produced by Kurzgesagt and posted on YouTube.  I previously wrote about this science YouTube channel here.  It's an excellent channel that produces a new, animated science video every couple of weeks.  The particular video I'm referring to is on the topic of black holes.

Why Black Holes Could Delete The Universe – The Information Paradox

At a very basic level, a black hole is a massive object packed into a tiny space.  Because this mass is packed into a very small space, the gravitational force is extremely large.  It is so large, in fact, that the mass is squeezed to an infinitesimally small space.  There's a distance away from this infinitesimally small space in which nothing, not even light, can escape.  This distance is referred to as the Schwarzschild radius or event horizon.

The cool thing about this video is that it goes well beyond this basic definition and explains the weird role that black holes can potentially play in the universe.  Give it a watch because it is very interesting!  The animation nature of this (and all videos on this channel) adds to the coolness!
